You may see the pictures of spiral stairs both for the huge home and small home. Surely, when you want to build the staircase with huge size, it will take a huge space, too. You need the spiral stairs dimensions in the huge size where it has full round shape from the base to the top or end of the stair. In the small space, the staircase can be built with a very simple design and sometimes it comes with a very cool design such adding slide beside the staircase. This is a brilliant idea to add.
